Alright, I'm pretty sure this will become my new house yeast for a couple reasons.
WLP001 is too slow to ferment, and too slow to clear. WLP002 just isn't quite clean enough, even fermented low. I get a slight apple/pear ester from it, which is fantastic in many beers, isn't ideal for cleaner styles. WLP007 was really close to taking the crown, but I find it has a slight tart character in lower gravity beers.
I've brewed about 5 batches now with WLP090, and I think it's perfect for me.
-It's very temperature tolerant, and still ferments quickly at 62-64F
-The yeast doesn't climb much. I haven't found the need for blow off tubes when fermenting cooler.
-It ferments very quick
-It flocs Very quick
-It's pretty damn clean. Not quite 001 clean, but still clean
-It re-pitches well, and I've found my lag times have decrease with subsequent pitches
The only downside I've found is the Krausen is very thick and sticky. Should it clog and air-lock or blow-off tube, it'll probably clog it good.
My final test for WLP090 is high gravity attenuation. I know WLP090 is rather alcohol-tolerant, but I need to see how it does fermenting a big DIPA where I need 8+ % ABV with a very low final gravity (1.009 or lower). Assuming it ferments a dry DIPA well, I'm looking at my new house yeast.
I like it a lot.
